BALlNG-PRESS.

sPEcIEIcA'rIoN forming part of Letters Patent No. 467,475, dated January19, 1892. Application filed June 24, 1891- Serial No. 397,296. (Nomodel.

To all whom it may concern:

Be it known that I, JOHN A. WRIGHT, a citizen of the United States,residing at Graylin g, in the county of Crawford and State of Michigan,have invented certain new and useful Improvements in Hay-Presses; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will en'- able others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to new and useful improvements in hay-presses;and it consists in a certain construction and arrangement of parts, ashereinafter more fully set forth, the essential features of which beingpointed out particularly in the claims.

The object of the invention is to provide a hay-press that is simple inconstruction, rapid and efiectual in its operation, andin which thearrangement of parts is such as to permit of the folding together of thepress-box and baleframe and the close coupling of the powerframethereto, enabling the entire device to be mounted on a single truck fortransportation. This object is attained by the mechanism illustrated inthe accompanying drawings, in which Figure 1 is a perspective view of myimproved hay-press in position for operation. Fig. 2 is a plan view ofthe same, aportion of the plunger-beam being broken out and the lid ofthe guide-box on the power-frame through which said beam passes beingturned back and the top of the power-frame being removed, showing theoperative mechanism. Fig. 3 is a central longitudinal section throughthe bale-frame, press-box, and plunger, the coiled spring in saidplunger showing in elevation. Fig. 4. is a plan view of the powermechanism in position the reverse of Fig. 2. Fig. 5 is a perspectiveview of said mechanism removed from the power-frame, the curved armbeingraised to better show the construction and position of parts. Fig.6 is a view of the device mounted for transportation.

Fig. 7 is a rear end elevation of the bale-frame.

Referring to the letters of reference, A indioates the power frame orcase, through which passes the vertical shaft B, that is journaled atits ends in the upper and lower faces, respectively, of said frame. Theupper end of said shaft extends through the frame A and is secured tothe inner end of the sweep O, as shown in Fig. 1, by means of which saidshaft is revolved. Located in said frame A is an oscillating base D,adapted to swing horizontally, and which is pivotally mounted on thevertical shaft B, that passes through said base at or near its geometriccenter (See Fig.5.)

E indicates a coupling-bar that connects the plunger-beam E with theoscillating base D, one end of said bar'E being pivoted to said base bymeans of the lip or flange b, extending horizontally from the under faceof said bar, and which enters the slot 1) in the base and is securedtherein by the bolt or rivet a, said bar E also having the nose 1)"extending from the upper face thereof and which projects onto the base Dwhen the parts are in the position shown in Figs. 4; and 5. Lying uponthe upper face of the base D is a plate F, adapted to slidelongitudinally thereon and having a rectangular opening through itscenter through which the shaft B passes loosely. d indicates a flangedepending from the under face of said plate F, said flange beingprovided with a tongue 0, extending from the side thereof and adapted tolie in the groove 0' in the edge of the base D, (see Fig. 5,) by whichmeans the plate F is secured in place on the base and permitted to slidethereon when acted upon by the nose I)" of the bar E, as hereinafterdescribed. One edge of said plate in its operation bears against thefriction-rollers a, mounted on the base D, which conduce to overcome thefriction between said parts. The plate F is also provided at one endwith the vertical shoulder d, extending from the upper face thereof,adapted to be engaged alternately by the ends e of the curved arm G,mounted on the shaft 13 and revolving therewith.

The plunger-beam E is coupled at one end to the bar E by means of thecoupling-head E", (shownin Fig 4,) and is adapted to pass through theguide-box F, secured to the frame A, the opposite end of said beam beingcoupled,

" extends-through the rear end of said plunger and is secured at 'i tothe yoke or bail K, that extends across the front of the press-box I.The ends of said bail pass through the posts h 011 each side of saidbox, in which they are adapted to be secured by the hand-screws J, thatengage the ends of said bail within the posts h, by which means the bailK maybe adjusted out or in to obtain the desired tension on the springH", the office of which is to return the plunger and plunger-beam afteran inward or press stroke has been made.

The upper face of the plunger H is formed of a depressible plate L,mounted on said plunger, the rear end of said plate being pivoted to thesides of the plunger, as shown at s, the forward end of said plate beingsupported by'the spring 3, that bears against the under face thereof.(Shown in Fig. 3.) By this arrangement the plate L is permitted toyield, thus preventing the wedging of the plunger in the press-box I.The under face of the plunger is provided with the frictionwheels f, onwhich said plunger rides when reciprocating in the press-box I.

In the upper face of the press-box I is the usual opening I, throughwhich hay is fed into said box ahead of the plunger H. Located slightlybelow the rear edge of the opening I'-in the box I is a shaft m, theends of which are journaled in the sides of said box and on which aremounted the diametrical wings 0, that revolve as the hay is forced underthem by the stroke of the plunger I-I, (shown by dotted lines in Fig.3,) and assist to carry the hay into the press-box and prevent itsclogging against the rear edge of the opening I. In the rear of theshaft m is located asmaller shaft n, carrying the wings 0', that revolveas.

thehay passes under them and prevent the clogging of the hay in the rearof the shaft m. The interior of the press-box on each side thereof isprovided with the vertical recesses m, that extend from the top to thebottom. Said recesses engage and retain the pressed hay, preventing itfrom springing back when the plunger is withdrawn.

P indicates the bale-frame, into which the hay is forced from thepress-box by the action of the plunger, and in which the hay is dividedinto bales and wired to retain it in form,as is commonly practiced. Thebale-frame is secured to the rear end of the press-box by means )t' thebin ges f and by the hooks if, coupling the tides thereof. Thisarrangement permits the iale-frame to be folded onto the press-box for'onvenience in transportation. The side bars N of the bale-frame thatextend longitudinally thereof are secured at their forward ends only,the rear ends thereof being adapted to be sprung in and are actuated bythe hand-screws R, that pass through the vertical posts T at the rear ofthe bale-frame and bear against the outer faces, respectively, of thespring-bars N, (clearly shown in Fig. 7,) whereby by operating thescrews R the bars N may be sprung in to reduce the dischargeopening atthe rear of the frame P, thereby offering a greater resistance to theaction of the plunger and increasing the compactness of the baledproduct.

In Fig. 1, which shows the parts in position for operation, S indicatesan anchoring-beam, to which the press-box I is secured. From the ends ofsaid beam the braces V extend to the power-frame A, whereby said partsare braced and securely held in place. The braces V, as well as theplunger-beam E, lie close to the ground, in which position of said partsthey may be easily stepped over by the horses when said horses arehitched to the sweep O and are traveling around the power-frame A tooperate the press.

Fig. 2 shows the normal position of the drivin g mechanism when readyfor operation, in which position of parts when the shaft B is revolvedone end e of the arm G will engage the shoulder d of the plate F, whichbeing slidingly attached to the base D, said base is thereby caused toswing, whereby the bar E, one end of which being pivoted at a to thebase, is moved endwise, actuating the plunger-beam E and causing aninward stroke of the plunger H and expanding the spring H. As theplunger reaches the end of its stroke the position of parts is such (seeFig. 4) that the nose I)" of the bar E will bear against the end of theplate F and slide said plate, which will disengage one end e of the armG from the shoulder cl of said plate, thereby releasing said arm fromengagement with the sliding plate and the base I), when the contractingof the spring H" will withdraw the plungerH, carrying back the beam Eand bar E, which will swing the base I) back to its former position.(See Fig. 2.) As the base swings back the curved guard G of the frame Awill engage the end of the plate F and slide said plate back to theposition shown in Fig. 2, when the opposite end 6 of the arm G willengage the shoulder d of said plate and the base D will be againactuated to cause another stroke of the plunger H, and so on, theplunger making two strokes to every revolution of the shaft B, whichvisgiven a continuous rotation by the horses traveling around the frame A.

When it is desired to transport the press, the beam S and braces V areremoved and the plunger-beam E detached from the plunger H and the barE. The hookst are uncoupled and the bale-frame P folded over onto thepress-box I, when the entire devicemay be mounted on a truck, as shownin Fig. 6,

the power-frame A being attached to the pressbox I by means of the hooks2, thereby securely retaining said parts in, place, in which positionthey occupy but a small compass and may be easily transported.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In combination with the power-frame, the oscillating base, the plateslidingly mounted thereon and having the shoulder d, the vertical shaft,the sweep and curved arm mounted on said shaft and made fast thereto,the coupling-bar pivotally coupled to said base and having the noseengaging with the a sliding plate, and the curved guard mounted on thepower-frame, for the purposes specified.

2. In. combination with the power-frame having the curved guard, theoscillating base, the plate having the shoulder cl slidingly mounted onsaid base,'the shaft, the sweep and curved arm made fast to said shaft,the

coupling-bar pivotally attached to said base and having the noseengaging with the sliding plate, the press-box, the rebounding plunger,and the plunger-beam coupling the plunger to the coupling-bar,substantially as specified.

3. In combination with the press-box, the plunger, the bail adjustablyattached across the forward end of the press-box, the coiled springlocated in the plunger, having one end attached thereto, its oppositeend being secured to said bail, and the pl anger-bar coupled to theplunger, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.
